FUEL ASSEMBLIES FOR RAPID SUPERGENERATING REACTORS WITH LIQUID METAL COOLING, DESIGNED TO CREATE A FUEL DISPERSION PATH IN THE EVENT OF AN ACCIDENT

摘要

A fuel assembly for a liquid metal fast breeder reactor having an upper axial blanket region disposed in a plurality of zones within the fuel assembly. The characterization of a zone is dependent on the height of the axial blanket region with respect to the active fuel region. The net effect of having a plurality of zones is to establish a dispersal flow path for the molten materials resulting during a core meltdown accident. Upward flowing molten material can escape from the core region and/or fuel assembly without solidifying on the surface of fuel rods due to the heat sink represented by blanket region pellets.
